<i><p>Physically Based Rendering: From Theory To Implementation, Third Edition</i> describes both the mathematical theory behind a modern photorealistic rendering system and its practical implementation. Through a method known as 'literate programming', the authors combine human-readable documentation and source code into a single reference that is specifically designed to aid comprehension. The result is a stunning achievement in graphics education.</p><p>Through the ideas and software in this book, users will learn to design and employ a fully-featured rendering system for creating stunning imagery. This completely updated and revised edition includes new coverage on ray-tracing hair and curves primitives, numerical precision issues with ray tracing, LBVHs, realistic camera models, the measurement equation, and much more. It is a must-have, full color resource on physically-based rendering.</p><ul><li>Presents up-to-date revisions of the seminal reference on rendering, including new sections on bidirectional path tracing, ray-tracing hair and curves, and micro faceted reflection models</li><li>Provides the source code for complete rendering systems allowing readers to get up and running fast</li><li>Includes a unique indexing feature, literate programming, that lists the locations of each function, variable, and method on the page where they are first described</li><li>Serves as an essential resource on physically-based rendering</li></ul>
